Accessibility Best Practices
Accessibility patterns for building inclusive React applications following WCAG standards. Contains 7 rules across 4 categories focused on semantic HTML, screen reader support, keyboard navigation, and user preferences.
When to Apply
Reference these guidelines when:
- Creating new UI components
- Building forms and interactive elements
- Adding dynamic content or notifications
- Implementing navigation patterns
- Reviewing code for accessibility
Rules Summary
Semantic HTML & Structure (HIGH)
semantic-html-landmarks - @rules/semantic-html-landmarks.md
Use semantic HTML elements for page structure.
// Bad: divs with class names
<div className="header">...</div>
<div className="nav">...</div>
<div className="content">...</div>
// Good: semantic elements
<header>...</header>
<nav aria-label={t("Primary")}>...</nav>
<main>...</main>
<footer>...</footer>
Screen Readers (MEDIUM)
screen-reader-sr-only - @rules/screen-reader-sr-only.md
Use sr-only class for visually hidden text.
// Icon-only buttons need accessible labels
<Button variant="icon" onPress={onClose}>
<XMarkIcon aria-hidden="true" />
<span className="sr-only">{t("Close")}</span>
</Button>
// Visually hidden section headings
<section>
<h2 className="sr-only">{t("Search results")}</h2>
<SearchResultsList />
</section>
aria-live-regions - @rules/aria-live-regions.md
Announce dynamic content changes to screen readers.
// Error messages - announced immediately
{
error && (
<p role="alert" className="text-failure-600">
{error}
</p>
);
}
// Status updates - announced politely
<div role="status" aria-live="polite">
{t("{{count}} results found", { count })}
</div>;
Keyboard & Focus (HIGH)
keyboard-navigation - @rules/keyboard-navigation.md
Use semantic elements for built-in keyboard support.
// Bad: div with onClick not keyboard accessible
<div onClick={handleClick}>Click me</div>
// Good: button has Enter/Space support
<button onClick={handleClick}>Click me</button>
// Good: react-aria Button handles everything
import { Button } from "react-aria-components";
<Button onPress={handlePress}>Click me</Button>
focus-management - @rules/focus-management.md
Show visible focus indicators and trap focus in modals.
// Always use focus-visible for focus styles
<button className="focus-visible:ring-2 focus-visible:ring-teal-600">
Click me
</button>;
// react-aria Modal handles focus trapping automatically
import { Modal, Dialog } from "react-aria-components";
<Modal isOpen={isOpen}>
<Dialog>{/* Focus automatically trapped here */}</Dialog>
</Modal>;
User Preferences (MEDIUM)
reduced-motion - @rules/reduced-motion.md
Respect prefers-reduced-motion setting.
import { usePrefersReducedMotion } from "~/hooks/use-prefers-reduced-motion";
// CSS approach
<div className="animate-bounce motion-reduce:animate-none">
Bouncing content
</div>;
// JS approach
function AnimatedCounter({ value }) {
let prefersReducedMotion = usePrefersReducedMotion();
if (prefersReducedMotion) return <span>{value}</span>;
return <CountUp target={value} />;
}
touch-targets - @rules/touch-targets.md
Ensure 44x44px minimum touch targets.
// Icon buttons need explicit sizing
<Button variant="icon" className="h-11 w-11">
<XMarkIcon className="h-5 w-5" />
<span className="sr-only">{t("Close")}</span>
</Button>
// Links need padding for tappable area
<Link to={href} className="block py-3 px-4">
{label}
</Link>
